Let's use .js extension. It's much more flexible than JSON and we can add comments.

Are we using them yet? I don't see them in eslintrc. Maybe we should add them later if we're not using yet.

eslint-config-fbjs requires it as peer dependencies

I've only added eslint-config-prettier so far to remove eslint-prettier conflict.
Edit: So for now we're effectively using eslint-config-fbjs & eslint-config-prettier

This changes the meaning - It was declaring a function before, now it's executing it. The after version looks more correct though.

yup. it's actually caught by the linter. Otherwise the function is never used

Feel free to merge this when you feel it's ready. We could add more rules later on/fix more issues. |

I'm going to add some more specific rules for libs that can cause bugs. Lot of linting errors are turned off at fbjs. |
|
Hmm in that case I wonder if fbjs is the right one to use. Let's get @JoelMarcey's opinion on this when he's available. But in the meanwhile we can merge this. |
